← A rope has points at 0.5, 1, 1.5 and 2.5 m, and a wave of wave number π rad/m is drawn at t = 0. What does this code print? import numpy as np; x = np.array([0.5, 1, 1.5, 2.5]); print(np.round(np.sin(np.pi * x), 2))Two speakers play 130 Hz and 134 Hz together for 2.5 s. What does this code print for the number of beats? f1, f2, T = 130, 134, 2.5; print(abs(f2 - f1) * T) →
